ORCHARD-HEATER.

Specieation of Letters Patent. i

Patented Mar. 31, 1914.

To all 'Lc/mm it may concern Be it known that we, ERNEST G. BUT'roN and F man M. HUN'rooN, b oth citizens of the 'Ii/'nited States, residing at Riverside, in the county of Riverside and State ofCalifornia, have invented new and useful Improvements in Orchard-Heaters, of which the following is a specification. i

This invention relates to orchard heat-v ers, and the principal object. is to provide van orchard heater in which the liquid fuel burnern tajclc provided' with'diagonally disp Y "ngs therein below its support in t over, togetherwith a hood for extinguishing the flame therein and covering the stack.v V

In the drawings accompanying this speciication and forming therewith the application for Letters Patent: Figure 1 is an elevation of the orchard heater showing the hood broken away, the burner 'stack in place, and a portion of the receptacle in section. F-i 2 is a plan view of the same, without tie hood. Fig. 3 is a detail sectional view of the damper. FiO. 4 is a plan view thereof, a portion of the damper being broken away. A

More specifically in the drawings, 5 designates the receptacle for containing oil, which is p'referably'of rectangular configuration having tapered sides and formed of an integral folded sheet of metal so there are no sea-ms to leak, the upper edge being turned back or lapped overl a wire to form a suitable rim 6. Mounted upon this receptacle. is a cover 7 also rectangular in form and 'pyramidal as to elevation and truncated, the truncation thereon forming a circular opening concentrically arranged toy the overlapping edges .8 ofthe cover, the edges of thecentral (aperture being raised or upturned to a certain extent to provide afwatershedgt) andalso a finished edge to receive the bead on the stack 15. `On one or more of the pyramidal faces of the metal cover the same is upset slightly and in this domed portion an arcuate slot 10 isstruck from a center, which center is provided with a pivot pin 11 on which is mounted the cupped damper 12, the openings 13 in this damper being arranged alli-Lto one side of the center and adapted. to register with the arcuate slot 10 when the damper is swung to the registering position by means of the handle 14 formed thereon, a number of napertures being preferred so that the amount of air entering each one of the apertures when registered and controlled by the damper may be regulated as desired or required.

The burner stack l5 sof-tubular construction and preferably of the slightly conical truncated form shown so that when inserted within the lcentral opening surrounded by the rimYQ-'the bead 26 formed thereon will rest upon therim 9 and the stack will besupported, the bead being preferably midway of its top 16 and bottom 17. Around the periphery of the burner and preferably a slight distance above theV upper'edge ofthe rim 9 are provided a seriesy of circular openings 10 whichv are adapted to admit the outside air with its oxygen direct to the interior of the burner. Below the supporting line and intermediate of the lower end 17 other apertures are provided, the first below the support being one or more circular apertures 19 preferably placed above the inclined and elongated slots 20 and 21, two pairs of these slots being shown in the burner and preferably oppositely disposed to one another and inclined in opposite directions, as clearly shown in Figs. l and 2.

To provide an extinguisher for the flame al hood 2Q is provided having a depending flange which fits loosely over the open top of the burne'r stack 15 and rests upon the cover adjacent the rim 9. It will thus be seen that when the hood is in placel and the damper closed no water can enter the receptacle and `cause injury to the contained oil,

it being customary to fill the heaters to'anticipatethe coming of a low temperature, and if rain precedes lthe latter, and water enters the receptacle the oil must be sep arated therefrom involving eXtra expense, or the heater may boil over. l

The inclined slots placed close to the bottom of the hiiriier increase the amount of draft automatically as the oil is loivered.

and heroines heavier and do not become rloggiuh as ivell as admit the air fi'oin the dampers lo llic burner stack in a whirling or spiraliii'oveiiieiit and causing a more intiiiiate and eil'icient mixture of the volatile elements.

What ive claim is:l

l. An orchard heater, comprising a. receptacle, a tri'incated cover having a. central aperture and adapted to closely fittlie upper rim of said receptacle and having draft i openings oppositely disposed .to each other, draft dainpers provided with a plurality of apertures adaptedto control and register in, a .damper pivoted on the center from which 4each said arcuate slot is struck having apertures therein, and means to niove nsaid damper to register said apertures with said arcuate slot or close the .sa-ine against the admission of water.

3. An orchard heater, comprising areceptacle; a cover therefor provided with domed portions each having an arcuate slot cut in its elevated portion, a rotatable draft dainper 'having openings to one side of a line intersecting the center, means to pivot said damper at its center at the point from which said arcuate slot is struck, and a handle on said damper to move the saine.`

enfin orchard heater, coinprisinga fuel receptacle and a pyran'iidal cover therefor having a centrally disposed opening therein and a plurality of draft openings, a burner stack mounted in said centrally disposed opening, ,said burner stack being provided with a plurality of inclined slots below said cover, and pivoted dainpers controlling the draft opei'iii'igs in said cover.

5. An orchard heater, eoinl'irising a fuel receptacle and a coi er therefor, said cover having a centrally disposed opening therein and a plurality of draft opeiiings,`and a burner slack mounted in the centrally disposed opeiiing, said burner stack being provided with a plurality of inclined slots below said cover.

6. An orchard heater, comprising a fuel receptacle and a pyrainidal cover therefor,

Said cover having a centrally disposed opening therein and a plurality of draft openings, a tapered burner stack mounted in said centrally disposed opening, said burner stack being provided with a plurality of circular draft openings above the cover, and

a plurality of inclined slots below said cover, and pivoted dainpers controlling the draft openings in said cover.

In witness that We claim the foregoing We have hereunto subscribed our names this llth day of July, 1913.
